摘要

By use of the model of transient flow, the mechanism of fluctuating pressure propagation in the cracks of a bed rock and the cause of the fluctuating uplift were investigated in detail, and the predicting formula for the maximum fluctuating uplift on rock blocks in a scour pool was deduced. To confirm the theoretical results, fluctuating uplift on various-sized rock blocks at the bottom of the scour pool was measured in the Three-Gorge spillway model.
